Built for Durability

AKMA motors are engineered for performance and longevity in tough washdown environments and uncertain outdoor conditions.

Unsurpassed durability starts with the motors’ hardened anodized aluminum coating that provides strong chemical resistance in a wide pH range to withstand common cleaning agents in washdown. You’ll find:

  • Coating that is less vulnerable to scrapes, dents, and paint flaking than conventional epoxy
  • Stainless-steel shaft with chromium oxide inlay maximizes lifetime of the shaft seal
  • Vented design and “one-piece” housing structure eliminates the O-ring to reduce risk of water ingress

Built for Cleanability

In both food and beverage contact zones and dry clean environments, AKMA motors incorporate critical design elements for more effective cleaning:

  • Smooth surface ensures simple cleanability in environments where cleanliness is essential
  • Round housing prevents contamination droplets from pooling
  • IP69K-rated sealing allows higher pressure exposure for food-grade environments

Easy-to-Clean, Durable Motion Systems for Food Processing and Packaging

The food processing and packaging industry plays a major role in ensuring that the final product is safe to consume. While food safety is a serious requirement, it also presents significant challenges for manufacturers. Frequent, high-pressure washdowns are essential to keep machines free from pathogens, yet these washdowns are often incomplete, ineffective and damaging to motors and other equipment. Common practices such as shielding or bagging motors to prevent damage are extremely time-consuming. Direct washdown of equipment that is not properly designed to prevent water ingress can lead to premature failure. Irregular and rough surfaces can harbor pathogens that are difficult to remove. Eliminate all these issues by employing these best practices for the design of a more hygienic and productive machine.
